7. 'Northern Exposure'
Fish-out-of-water shows have been a staple of television for decades: Just think about The Beverly Hillbillies (Southerners in Beverly Hills!) or Green Acres (Beverly Hills residents in the South!). So there wasn't anything all that original about Northern Exposure's basic premise of a New York doctor who moves to a small town in Alaska. What made the show great was its brilliant execution. Rob Morrow played the doctor, but as Exposure continued, it began focusing more and more on the townspeople. It never generated killer ratings, but the critics loved it and a cult audience followed.
